Broadband optical limiter based on nano-graphene and method of fabricating same

摘要

The present invention in one aspect relates to a low-cost, nano-graphene based broadband optical limiter with limiting properties superior to current standards, carbon fullerenes (C₆₀) solutions and carbon black suspensions. The broadband optical limiter includes a plurality of graphene nano-sheets, and a base material in which the plurality of graphene nano-sheets is distributed. The base material can be liquid or gel matrix.
